Launched 47 years ago, Voyager 1 is flying on an outbound trajectory 24 billion kilometers (22 light-hours) from Earth. It was designed to work for 5 years. "Voyager's ground team discovered a single chip responsible for storing a portion of the on-board computer (FDS) memory stopped working, probably due to either a cosmic ray hit or a failure of aging hardware. That took out a section of memory. What they have to do is relocate that code into a different portion of the memory, and then make sure that anything that uses those codes, those subroutines, know to go to the new location of memory, for access and to run it. Only about 3 percent of the FDS memory was corrupted by the bad chip, so engineers needed to transplant that code into another part of the memory bank. But no single location is large enough to hold the section of code in its entirety. So the Voyager team divided the code into sections for storage in different places in the FDS." https://lnkd.in/g8w6wCvZ
It's amazing how Voyager 1 is still going strong after 47 years! The team's innovative approach to relocating the affected code shows their resilience and problem-solving skills. Really a great example of human adaptability in the face of challenges.. Great stuff keep on posting! PS Their approach reminds me of the concept of cognitive flexibility, which is the ability to switch between different tasks or ways of thinking.

Love this old school programming! Back when every byte counted. Good to see it’s still alive.

3moThat was a brilliant idea to put this map on the ship. When the aliens get it, they will pay us a friendly visit.
